How does Accelerator choose the solver for a specific project?

Accelerator chooses the solver for a specific project according to the project size and convergence settings.

For WindSim 11 projects: you could always choose all the different solvers.

For WindSim 12 projects: we changed it, so that projects <4M cells would always be GCV and >=4M cells would be the ParallelGCV.

So if you on the WindSim 12 Desktop set the solver to GCV and upload it. Accelerator will change this to ParallelGCV if the project is larger than 4M cells. You can always change it back yourself to GCV if you want to.

There are some other settings that are not available in the Accelerator GUI, then we just use the settings that were set in the Desktop version. But solver and iterations settings that you see in Accelerator are the ones that are used.
